The generated OSD signal may include various data including the user interface screen window of the image providing device 50, various menu screen windows, widgets, and icons.

The OSD generator 340 may generate a pointer which can be displayed on the display, based on a pointing signal input from the remote control device 400. In particular, the pointer may be generated by a pointing signal processor (not shown), and the OSD generator 340 may include the pointing signal generator. Of course, it is possible to provide the pointing signal processor (not shown) separately from the OSD generator 340.

The mixer 345 may mix the OSD signal generated by the OSD generator 340 with an image signal processed and decoded by the image processor 320. Herein, each of the OSD signal and the decoded image signal may include at least one of a 2D signal and a 3D signal. The mixed image signal is provided to the frame rate converter 350.

The frame rate converter (FRC) 350 may convert the frame rate of an input image. The FRC 350 may output the frame rate without performing separate frame rate conversion.

The formatter 360 may change the format of an input image signal to a predetermined format.

For example, the formatter 360 may arrange a left image frame and right image frame of a 3D image produced through frame rate conversion. The formatter 360 may output a synchronization signal Vsync to open the left eye glass or right eye glass of a 3D view apparatus (not shown).

The formatter 360 may change the format of a 3D image signal. For example, the formatter 360 may change the format of the 3D image signal to one of various 3D formats.

The formatter 360 may convert a 2D image signal into a 3D image signal. For example, the formatter 360 may detect an edge or a selectable object in a 2D image signal, and separate and generate the object according to the detected edge of the selectable object as a 3D image signal. In this case, the generated 3D image signal may be separated into a left image signal L and a right image signal R to be aligned.

An audio processor (not shown) in the first processor 170 may process a demultiplexed voice signal. To this end, the audio processor (not shown) may include various decoders.

The audio processor (not shown) in the first processor 170 may perform processing such as adjustment of bass, treble, and volume.

The data processor (not shown) in the first processor 170 may perform data processing on a demultiplexed data signal. For example, if the demultiplexed data signal is a coded data signal, the data processor (not shown) may decode the data signal. The coded data signal may be electronic program guide (EPG) information containing broadcast information such as a start time and end time of a broadcast program broadcast on each channel.

The block diagram of the first processor 170 shown in FIG. 3 is simply illustrative. Constituents of the block diagram may be integrated, added or omitted according to the specifications of the first processor 170.

In particular, the frame rate converter 350 and the formatter 360 may not be provided in the first processor 170. Instead, they may be provided individually or provided as one separate module.

FIG. 4 illustrates a method for controlling the remote control device of FIG. 2.

As shown in FIG. 4(a), a pointer 205 corresponding to the remote control device 400 may be displayed on the display 180.

The user may move the remote control device 400 up and down, left and right (FIG. 4(b)), or back and forth (FIG. 4(c)) or rotate the same. The pointer 205 displayed on the display 180 of the image providing device corresponds to movement of the remote control device 400. As shown in the figure, since the pointer 205 moves according to movement of the remote control device 400 in 3D space, the remote control device 400 may be referred to as a spatial remote control or a 3D pointing device.

FIG. 4(b) illustrates a case where the pointer 205 displayed on the display 180 moves to the left when the user moves the remote control device 400 to the left.

Information about movement of the remote control device 400 sensed through a sensor of the remote control device 400 is transmitted to the image providing device. The image providing device may calculate coordinates of the pointer 205 based on the information about the movement of the remote control device 400. The image providing device 50 may provide the pointer 205 such that the pointer 205 corresponds to the calculated coordinates. Thereby, the pointer 205 may be displayed on the display 180.

FIG. 4(c) illustrates a case where the user moves the remote control device 400 away from display 180 while pressing down a specific button on the remote control device 400. In this case, a selected area of the display 180 corresponding to the pointer 205 may be zoomed in and displayed with the size thereof increased. On the other hand, when the user moves the remote control device 400 closer to the display 180, the selected area may be zoomed out and displayed with the size thereof reduced. Alternatively, the selected area may be zoomed out when the remote control device 400 moves away from the display 180, and may be zoomed in when the remote control device 400 moves closer to the display 180.

For example, the remote control device 400 may include an RF module 421 capable of transmitting and receiving signals to and from the image providing device 50 according to an RF communication standard. The remote control device 400 may further include an IR module 423 capable of transmitting and receiving signals to and from the image providing device 50 according to an IR communication standard.

The remote control device 400 may transmit a signal containing information about movement of the remote control device 400 to the image providing device 50 via the RF module 421.

In addition, the remote control device 400 may receive a signal from the image providing device 50 via the RF module 421. When necessary, the remote control device 400 may transmit commands related to power on/off, channel change, and volume change to the image providing device 50 via the IR module 423.

The user input unit 435 may include a keypad, a button, a touchpad, or a touchscreen. The user may input a command related to the image providing device 50 by manipulating the user input unit 435. If the user input unit 435 includes a hard key button, the user may input a command related to the image providing device 50 by pressing the hard key button. If the user input unit 435 includes a touchscreen, the user may input a command related to the image providing device 50 by touching a soft key on the touchscreen. The user input unit 435 may include various kinds of input means such as a scroll key and a jog key, but it should be noted that this embodiment does not limit the scope of the present invention.

The sensor unit 440 may include a gyro sensor 441 or an acceleration sensor 443. The gyro sensor 441 may sense information about movement of the remote control device 400.

For example, the gyro sensor 441 may sense information about movement of the remote control device 400 with respect to the X, Y and Z axes. The acceleration sensor 443 may sense information about the movement speed of the remote control device 400. The sensor unit 440 may further include a distance measurement sensor to sense a distance to the image providing device 50 or the display 180.

The output unit 450 may output an image signal or voice signal corresponding to manipulation of the user input unit 435 or a signal transmitted from the image providing device 50. The user may recognize, via the output unit 450, whether the user input unit 435 is manipulated or the image providing device 50 is controlled.

For example, the output unit 450 may include an LED module 451 configured to be turned on when signals are transmitted to and received from the image providing device 50 via the wireless communication unit 425, a vibration module 453 configured to generate vibration, a sound output module 455 configured to output sound, or a display module 457 configured to output an image.

The power supply 460 supplies power to the remote control device 400. If the remote control device 400 does not move for a predetermined time, the power supply 460 may stop supplying power to save power. The power supply 460 may resume supply of power when the predetermined key provided to the remote control device 400 is manipulated.

The storage unit 470 may store various kinds of programs and application data necessary for control or operation of the remote control device 400. When the remote control device 400 wirelessly transmits and receives signals to and from the image providing device 50 via the RF module 421, the remote control device 400 and the image providing device 50 may transmit and receive signals in a predetermined frequency band. The processor 480 of the remote control device 400 may store, in the storage unit 470, information about, for example, a frequency band enabling wireless transmission and reception of signals to and from the image providing device 50, which is paired with the remote control device 400, and reference the same.

The processor 480 controls overall operations related to control of the remote control device 400. The processor 480 may transmit, via the wireless communication unit 425, a signal corresponding to manipulation of a predetermined key of the user input unit 435 or a signal corresponding to movement of the remote control device 400 sensed by the sensor unit 440 to the image providing device 50.

The user input interface unit 150 of the image providing device 50 may include a wireless communication unit 151 capable of wirelessly transmitting and receiving signals to and from the remote control device and a coordinate calculator 415 capable of calculating coordinates of the pointer corresponding to operation of the remote control device 400.

The user input interface unit 150 may wirelessly transmit and receive signals to and from the remote control device 400 via an RF module 412. In addition, the user input interface unit 150 may receive, via an IR module 413, a signal transmitted from the remote control device 400 according to an IR communication standard.

The coordinate calculator 415 may calculate coordinates (x, y) of the pointer 202 to be displayed on the display 180, by correcting the unstable position of a hand or an error in a signal corresponding to operation of the remote control device 400 which is received via the wireless communication unit 151.

The transmitted signal of the remote control device 400 input to the image providing device 50 via the user input interface unit 150 is transmitted to the processor 180 of the image providing device 50. The processor 180 may determine information about an operation of the remote control device 400 or manipulation of a key from the signal transmitted from the remote control device 400, and control the image providing device 50 according to the information.

As another example, the remote control device 400 may calculate coordinates of the pointer corresponding to movement thereof and output the same to the user input interface unit 150 of the image providing device 50. In this case, the user input interface unit 150 of the image providing device 50 may transmit, to the processor 180, information about the received coordinates of the pointer without separately correcting the unstable position of the hand or error.

As another example, in contrast with the example of the figure, the coordinate calculator 415 may be provided in the first processor 170 rather than in the user input interface unit 150.

FIG. 6 illustrates storing and reproducing a broadcast signal in an image providing device according to an embodiment of the present invention, and FIG. 7A to 16 illustrate operation of FIG. 6.

Referring to FIG. 6, the first circuit board 100 may receive a broadcast signal through the broadcast receiver 105. The received broadcast signal may be a terrestrial broadcast signal, a cable broadcast signal, or a broadcast signal received over a network.

When an input for receiving broadcast is provided, the first processor 170 may perform signal processing on the received broadcast signal.

For example, the first processor 170 may extract, from the received broadcast signal, at least one of channel information, broadcast program name information, broadcast start time information, and broadcast end information, add the extracted information to a broadcast signal, and output the broadcast signal to the first interface unit 125.

As another example, the first processor 170 may extract a decoded broadcast image from the input broadcast signal by performing image signal processing, and output the extracted broadcast image to the first interface unit 125.

According to the input for saving broadcast, the first interface unit 125 may transmit the input broadcast signal or broadcast image to the second interface unit 225 in the second circuit board 200.

According to the input for saving the broadcast, the second processor 270 may control a broadcast signal or broadcast image input from the second interface unit 225 to be stored in the second storage unit 240.

In storing the signal or image in the second storage unit 240, the second processor 270 may extract added information from the input broadcast signal and control the extracted information and the broadcast signal to be stored in the second storage unit 240. Alternatively, the second processor 270 may encode the input broadcast signal image and control the encoded broadcast image to be stored in the second storage unit 240.

According to the input for saving broadcast, the received broadcast content may be stably stored in the second storage unit 240 in the second circuit board 200, which has a large storage space.

In particular, when the user is in the outdoor environment, the first circuit board 100 and second circuit board 200 in the image providing device 50 may be activated at the broadcast time according to reservation of broadcast saving, and stably store received broadcast content in the second storage unit 240 in the second circuit board 200, which has a large storage space, according to the input for saving the broadcast.

Alternatively, when the user watches a screen of other content through the image providing device 50, received broadcast content may be stably stored in the second storage unit 240 in the second circuit board 200 which has a large storage space according to an input for saving broadcast. In particular, the first processor 170 and second processor 270 may be separated from each other such that signal processing on content which is being watched is performed by the first processor 170, and signal processing on broadcast content to be stored is performed by the second processor 270 or not separately performed. Thereby, signal delay does not occur in performing signal processing.

If the other content screen is a broadcast screen of another channel that is being watched, signal processing of the broadcast signal of another channel is performed by the first processor 170, signal processing of broadcast content to be stored is not performed or is performed by the second processor 270. Thereby, time delay does not occur in performing signal processing.

If an input for playing the stored broadcast content is provided, the first circuit board 100 and second circuit board 200 are activated according to the input for playing the broadcast content.

In addition, the second processor 270 may receive a broadcast signal or broadcast image stored in the second storage unit 240, and provide the same to the second interface unit 225.

At this time, separate signal processing may be performed. For example, the second processor 270 may decode the encoded broadcast signal or broadcast image. Alternatively, the second processor 270 may extract at least one of channel information, broadcast program name information, broadcast start time information, and broadcast end information from the broadcast signal, add the extracted information to a broadcast signal, and output the broadcast signal to the second interface unit 225.

According to the input for playing broadcast content, the second interface unit 225 may transmit the input broadcast signal or broadcast image to the first interface unit 125 in the first circuit board 100.

According to the input for playing the broadcast content, the first processor 170 may perform signal processing on the broadcast signal or broadcast image input from the first interface unit 125, and output a broadcast image or broadcast sound which can be reproduced.

The output broadcast image is displayed through the display 180, and the broadcast sound is output through the audio output unit 185.

As described above, the broadcast content stored in the second storage unit 240 in the second circuit board 200, which has a large storage space, may be stably reproduced according to the input for playing the broadcast content.

The first processor 170 may run a first OS, using the first OS-related data stored in the first storage unit 140. In addition, the first processor 170 may execute various applications which are based on the first OS.

For example, the first OS-based applications may include at least one of an application related to external input, a broadcast guide application, an application related to stored broadcast content, a Bluetooth application, a reservation application, a digital video recorder (DVR) application, a hotkey application, an application of Internet phone call service according to connection to a network, a VOD service application, a web album service application, a social networking service (SNS) application, a location-based service (LBS) application, a map application, a web search application, a game application, a schedule management application, and the like.

The first OS may be a UNIX-based OS, a Web-based OS, or the like.

The second processor 270 may run a second OS using data related to the second OS stored in the second storage unit 240. In addition, the second processor 270 may execute various applications which are based on the second OS.

Herein, the second OS may be different from the first OS and may be Windows, macOS, UNIX, or the like.

FIG. 17 illustrates an image providing system according to another embodiment of the present invention.

Referring to FIG. 17, an image providing system 10 b according to an embodiment may include a terminal 600, a server 500, and an image providing device 50 b.

The terminal 600 may connect to the server 500 according to an input web address, receive information for connection to a personal server from the server 500, and display a screen for connection to the personal server.

When login information is input on the personal server connection screen, the terminal 600 may transmit login information to the server 500, receive personal server list information corresponding to the login information from the server 500, and display a personal server list screen.

When a personal server is selected on the displayed personal server list screen, the terminal 600 makes a request to the server 500 for network information corresponding to the selected personal server.

The server 500 transmits the network information corresponding to the requested personal server to the terminal 600, and the terminal 600 receives the network information corresponding to the personal server from the server 500. Then, the terminal 600 may connect to the selected personal server using the received network information.

Herein, the personal server may correspond to the image providing device 50 b shown in FIG. 17. That is, when one personal server is selected, the terminal 600 may connect to the corresponding image providing device 50.

The image providing device 50 b, which is a device for providing images, may provide a predetermined image to an external device.

In particular, the image providing device 50 b may receive a broadcast signal, and perform signal processing thereon. Thereby, the image providing device 50 may provide streaming of a broadcast content, or transmit content stored in the memory. That is, the image providing device 50 may operate as a personal server.

To implement transmission of content to the outside, the image providing device 50 b may have network information. Herein, the network information may include public IP information and private IP information.

To connect to an external server 500 or the terminal 600, the image providing device 50 b may connect to a network 700 via an AP device (not shown).

Herein, network information corresponding to the AP device (not shown) may include public IP information.

A device, particularly, the image providing device 50 b that is connected to the AP device (not shown) in a wired or wireless manner constitutes an internal network in the AP device (not shown), and thus may be assigned a private IP by the AP device (not shown). Accordingly, the network information corresponding to the image providing device 50 b in the AP device (not shown) may include private IP information.

That is, in order to connect to the external server 500 or the terminal 600, the image providing device 50 b may have public IP information corresponding to the AP device (not shown) and private IP information corresponding to the image providing device 50 b.

Thereby, when one personal server is selected, the terminal 600 receives, from the server 500, the network information of the image providing device 50 b corresponding to the personal server, namely the public IP information and the private IP information, and connects to the image providing device 50 using the network information.

In addition, the terminal 600 may receive the shared content list information from the connected image providing device 50 b, and display a shared content list screen. If the user selects any one content item from the list, the terminal 600 may make a request for transmission of the content to the connected image providing device 50 b, and receive the content

Thereby, the user of the terminal 600 may remotely connect to the image providing device 50 b, which is a personal server, receive desired content and easily watch the same. Accordingly, user convenience may be enhanced.

In particular, if a web address is input on the web browser without a separate application installed on the terminal 600, the terminal 600 may be provided with a screen for connection to a personal server from the server 50 b. After being logged in, the terminal 600 may be provided with a personal server list screen, and easily connect to the selected personal server, namely the image providing device 50 b.

In particular, since the terminal 600 may receive private IP information of the image providing device 50 b from the server 500, connection to the image providing device 50 b is facilitated.

Meanwhile, the terminal 600 may conceptually include a fixed terminal or a mobile terminal.

When the terminal 600 is connected according to the web address input, the server 500 may provide a screen for connection to a personal server.

The server 500 may have a plurality of web addresses, and provide server connection screens for different user interfaces according to the respective web addresses.

For example, when a web address for a PC is input, the server 500 provides the server 500 with a server connection screen corresponding to a first resolution. When a web address for a mobile device is input, the server 500 may provide the server 500 with a server connection screen corresponding to a second resolution which is lower than the first resolution.

As another example, when a first web addresses are input, a server connection screen corresponding to the first web address may be provided to the server 500. When a second web address is input, a second server connection screen corresponding to the second web address may be provided to the server 500.

When login information is received from the terminal 600, the server 500 may provide corresponding personal server list information to the terminal 600 based on the login information.

If a personal server list corresponding to the login information is pre-stored, the server 500 may provide corresponding personal server list information to the terminal 600 based on the login information.

The memory 540 (see FIG. 19A) in the server 500 may store login information about a person, device information about the image providing device, server list information corresponding to the login information, and network information corresponding to each personal server. Herein, the network information may include the aforementioned public IP information and private IP information.

When a request for network information about a specific personal server in the personal server list is received from the terminal 600, the server 500 may perform a control operation to transmit, to the terminal 600, network information about the specific personal server, namely public IP information and private IP information. The server 500 may further transmit device information and account information (account ID).

Meanwhile, the server 500 may frequently connect to the image providing device 50 b to receive network information about the personal server, namely the image providing device 50 b, and perform a control operation to update the network information.

In contrast with the AP device (not shown), which is kept turned on, the image providing device 50 b is turned on only when it is used. Accordingly, the private IP information may frequently change. To update such private IP information, the server 500 may connect to the image providing device 50 b to receive new network information, in particular, private IP information whenever it is allowed, in particular, whenever it is turned on.

The server 500 may store the new network information as updated network information for the image providing device 50 b.

The server 500 may transmit the updated network information to the terminal 600 when the terminal 600 requests the same. The terminal 600 may receive the updated network information from the server 500 without a separate procedure, and easily connect to the image providing device 50 b, which is a personal server.

The server 500 may provide advertisement information when it provides information for connection to a personal server. In addition, after being logged in, the server 500 may provide the advertisement information along with the personal server information.

The server 500 may vary the type and attributes of the provided advertisement information depending on whether logging has been performed or not. That is, after logging is performed, the server 500 may provide customized advertisement information to the user.

The first circuit board 100 b may be separated from the second circuit board 200 b. Thereby, when one of the two circuit boards, in particular, the second circuit board 200 b malfunctions, broadcast images may be stably provided through the first circuit board 100 b.

The processor of the second circuit board 200 b is better than the processor of the first circuit board 100 b in terms of processing speed, processing capacity, and the like. Thereby, the second circuit board 200 b may be responsible for high-performance functions, for example, image capture through a camera, gesture recognition, Web connection, and executing games.
